Abstract: 1,181,566. Wire braided hose. RAYBESTOS-MANHATTAN Inc. 19 June, 1967 [20 June, 1966], No. 28106/67. Heading F2P. In a tubular wire braided hydraulic hose reinforcement comprising a plurality of braided strands, each strand consists of a multi-layered bundle of randomly arranged metal wires 36, the strands filling substantially 100% of available strand space, each strand having a permanent wounded configuration characterized by a continuous, substantially repetitive variation in cross-section conforming to the curvature of the adjacent transverse strands to thereby provide a smoothly curving disposition of all the strand wires. As shown, a reinforced hose 28 having improved static burst and impulse performance, comprises an inner tube 30 made of rubber or plastics and a surrounding braid 32 the strands 34 of which are formed of a relatively large number, e.g. 32, of small diameter wires 36 irregularly arranged in bundles, the stranded wires flowing smoothly over and under each other without the formation of any sharp bends. Since the strands occupy 100% of the strand space uniform tensioning and accurate alignment of the wires is unnecessary, a relatively greater number of wires being incorporated in a single strand. The strands are preferably braided two overtwo under at the neutral braid angle of 54‹ 44<SP>1</SP>, the wire size preferably being within the range of 0.004 to 0.012 inch. The impulse performance may be substantially increased by subjecting the hose to twice the ordinary working pressure for a relatively short period of time, e.g. a few seconds to a minute, or more. The inner tube 30 is advantageously made of polytetrafluoroethylene. The braid may be covered by another similar braid, or by one of conventional design.

Title: Detection of surface defects in elongate metallic members
IPC: G01N27/90
Filed: 1974-06-27
Abstract: 1475517 Eddy current testing BRITISH STEEL CORP 22 May 1975 [27 June 1974] 28597/74 Heading G1N In an eddy current testing apparatus both surface defects and probe-surface spacing are measured. A probe coil 1 forming part of the tuned circuit of an oscillator 13 is arranged adjacent to a surface of a steel billet to be tested whereby the frequency and amplitude of the oscillator output are dependent on both surface defects and probe-surface spacing, the amplitude content being primarily dependant on probesurface spacing whereas frequency content is more dependant on surface defects than the spacing. The oscillator output is fed to two channels one of which, the frequency channel, includes a tuned high frequency limiter amplifier 4 which is coupled via transformer 17, a frequency discriminator and a band pass filter to one input of a summing amplifier and one input of a difference amplifier, Fig. 1 (not shown). The other channel, the amplitude channel includes a low frequency amplifier 19 whose input is coupled to the oscillator output by diode detector 18, and output is applied to amplifier 20 designed to add a negative voltage to the input. Amplifier 20 output is then applied via a low pass filter and a high pass filter to the other input of the summing amplifier the output of which is essentially indicative solely of surface defects. The output of the low pass filter is also applied to a second input of the difference amplifier the output from which is essentially indicative solely of probe-  surface spacing, a D.C. offset being also applied such as to produce zero output from the amplifier when the probe coil is in free air. The output signal from the difference amplifier is then used to compensate the defect signal from the summing amplifier for probe-surface space changes. Two probe coils may be mounted in a rotatable head to scan the surface of the billet, Fig. 4 (not shown), there being four such heads.

Abstract: 187,626. Ramondo, E. Oct. 22, 1921, [Convention date]. Spring wheels. - A ring a attached to the rim of the wheel moves freely between discs d attached to the hub. The vertices v of three or more cone-shaped members i are universally jointed to bearings e which slide in casings u fixed to the ring a. The bases o of the members i bear on balLs h fixed to a hubflange m, while the rims thereof bear on a ring u resiliently fixed to one of the discs d b y axial springs r. When the hub and rim are concentric, the axes of the members i are parallel with the hub and their bases bear evenly on the ring u. When an obstruction is met, the ring a and consequently the members i, are displaced to a position similar to that shown in Fig. 3. The ring u is thus axially displaced against the springs r, which ultimately correct the displacement. Compound spring elements as shown in Fig. 4, in which the inner spring only acts during excessive displacement, or air cushions, may replace the springs r.
